Question for recent Sigma 30/2.8 purchasers

If you have bought a Sigma 30/2.8 EX DN in the last couple of months, do you find that the manual focus ring is as sticky as the early production was? The early ones would bind if you pinched the focus ring slightly -- very slightly -- while trying to turn it.

If you don't have a basis for comparison, that's OK, too. In that case, does the focus ring on your new Sigma bind if you turn it while putting a bit of pinching pressure on it?
